DESCRIPTION

1. Field of the Invention

An object of the invention is an autonomous modular bathroom designed to be installed in a room.

The invention relates to the technical field of sanitation and more particularly to autonomous and personal modular bathrooms designed to be installed in a room of a dwelling not designed for this purpose.

2. Prior Art

Bathrooms designed to be installed in a room of a dwelling are known, such as those described in the documents DE 20 2005 002 1 16 (Stefan Weber), GB 2,467,266 (RESIN GUN SA), GB 2,579,646 (Moriot Marcel and Robert Daniel), GB 2,671,961 (AMILHAU Martine), GB 2,735,674 (CITIRA SPIE SA), GB 2,690,831 (TBS FABRICATIONS LIMITED) AT 2006 203 623 (Norma McCulloch), U.S. 2003/0140571 (J & K MANUFACTURING Inc.), U.S. 2009/0100769 (Jeffrey L. Barrett & Adam Hedgcock), U.S. 2008/0289099 (Jerald P. Skinner), U.S. Pat. No. 5,652,976 (Clair L. HOPPER). These bathrooms can be one-piece or prefabricated and generally comprise a washbasin, a shower and a toilet. In order to dispose of wastewater, the bathrooms are equipped with discharge connectors for connecting the sanitary facilities to the sewage disposal network of the dwelling or of a collective sewer system.

These bathrooms require the installation of wastewater evacuation ducts sewage in the room of the dwelling where they are installed. But the instalation of an evacuation duct in a room is often complex and expensive and requires carrying out major work. In fact, in contrast to the water current supply conduits that generally have a diameter less than 15 mm, the evacuation ducts have a large diameter, generally greater than 40 mm for a shower and 100 mm for a toilet, thereby complicating their passage through a wall. Furthermore, for the flow of the wastewater to be effective, the evacuation ducts must be inclined downtoward from there end. In addition, renters of their dwelling must first obtain the consent of the owner before being able to carry out such work.

Also known are the bathrooms to be installed in camping vehicles of the trailer, camper or motorhome type. This type of bathroom is for example described in the document U.S. Pat. No. 5,742,956 (Alan Tarver). These bathrooms enable dispensing with a connection to a home wastewater evacuation network by evacuating it by gravity and by it in a storage reservoir located below the vehicle floor.

However, the adaption of such a solution to a dwelling would necessarily imply carrying out work in the floor so as to make a specific location for receiving a storage reservoir of the wastewater. However, the creation of a specific location in the floor, in addition to being complex and costly, can weaken the aforementioned floor. Furthermore, when placed under the floor, the reservoir becomes inaccessible to the user and difficult to empty.

Faced with this situation, a pricipal objective of the invention is to provide an autonomous modular bathroom designed to be installed on the floor in a room of a dwelling, and enabling to dispense with the installation of wastewater evacuation in the aforementioned room or the integration part of a reservoir in the floor of the aforementioned room and optionally the installation of hot water conduits from the water heater of the dwelling.

The sanitary unit is arranged so that a user can take a shower while sitting on the seat (22). The waste water generated by this shower can be discharged directly via the bowl of the toilet (6) and/or the slatted floor (3) positioned around the aforementioned toilet and/or via the basin of the shower (8) if the aforementioned toilet is positioned in the aforementioned basin. The entire floor (3) can act as the shower basin (8) and optionally be doubled in thickness by a grating. The shower can be taken either standing or sitting in folding the seat (22) and by maneuvering the washbasin (7): in upper storage position (first variant), by truning it down in its drawer (second variant) or by laterally moving it in the first use position (third variant).

b. Second Implementation Mode.

In this implementation mode shown schematically in FIG. 11, the enclosure of the bathroom (1) is formed from a first sanitary unit enclosing the toilets (6), a second sanitary unit enclosing the washbasin (7), and a third sanitary unit enclosing the shower (8), the aforementioned sanitary units being independent.

It would also be possible to add one or multiple other sanitary units and/or consolidate multiple sanitary facilities in the same module.

c. Other Characteristics of the Sanitary Unit(s).

The sanitary unit(s) can also include complementary sanitary facilities, of the wheelchair ramp, height adjustable shower seat, support bar, crane, etc., type

In the case where the floor (3) of the bathroom (1) is raised relative to the floor of the room, the sanitary unit(s) can be equipped with a ramp whose inclination meets the standards in force, allowing easy access to persons in wheelchair.

3. Other Features of the Bathroom.

The following technical features are suitable for the enclosure of the bathroom, whatever its implementation mode.

As shown in FIG. 14, the enclosure can be mounted on wheels (5) so that it can be moved easily in the room. The wheels (5) can be free for manual movement or motorized for automatic movement. This can be particularly be very useful to get the bathroom (1) closes to a user with reduced mobility, or for moving the aforementioned bathroom from the bed of a first user to the bed of a second user when two users cohabit in the same home.

As shown schematically in FIGS. 15 and 16, the enclosure of the bathroom (1) can be telescopic so as to reduce its bulk when not in use. In such a configuration, the enclosure comprising a first movable part (P1) forming facade adapted to slide in a second fixed part (P2) wherein is positioned the sanitary facilities (6, 7, 8). The first part (P1) slides in the second part (P2) by means of slides, rails, wheels, etc. The movement of the first part (P1) can be performed manually or automatically if a motor is provided. This solution enables division of the width of the enclosure by two.
